HEAT-SEALING COMPOUND FOR SEALING ALUMINIUM FOIL AND POLYETHYLENE TEREPHTHALATE FILM TO POLYPROPYLENE, POLYVINYL CHLORIDE AND POLYSTYRENE CONTAINERS

摘要

The invention relates to a heat-sealing system consisting of an olefin polymer or olefin copolymer A, a methacrylate copolymer B, a graft polymer AB that is composed of the aforementioned components, a polyester C and an optional polymer D or an optional polymer blend DA, in addition to a solvent or solvent mixture L. The heat-sealing system is characterised by a high heat resistance, excellent barrier properties and short sealing times in relation to various plastics and aluminium foil or PET film.
